Thailand Employee Welfare Fund: What Employers Need to Know

Thailand’s Employee Welfare Fund is no longer a future obligation. Contributions began on 1 October 2026.

The Fund has existed on paper since the Labour Protection Act B.E. 2541 (1998). It took more than a quarter of a century, and one last-minute postponement, to switch it on. For employers that have not yet acted, the first remittance is now weeks away.

Here is what you need to know.

What the Fund is for

The Employee Welfare Fund (EWF), or กองทุนสงเคราะห์ลูกจ้าง, is a joint savings scheme. Employers and employees both contribute. When employment ends, the employee receives their own savings, the employer’s contributions and the investment returns.

According to the Department of Labour Protection and Welfare (DLPW), that money is paid as a lump sum within 25 days. The aim is a financial cushion between jobs, or support for families when an employee dies.

It sits alongside social security and statutory severance pay. It does not replace either.

Who must contribute

The Fund covers private-sector employers with 10 or more employees that do not already operate a provident fund.

That exemption deserves care. The Labour Protection Act lets employers stay outside the Fund if they provide a provident fund, or comparable assistance on termination or death. Employers with a provident fund that does not cover every employee should check whether the uncovered staff fall into the Fund.

How much, and when

The rates are set by ministerial regulation:

Period	Employer	Employee
1 October 2026 to 30 September 2031	0.25% of wages	0.25% of wages
From 1 October 2031	0.50% of wages	0.50% of wages

The employer deducts the employee’s share from wages, adds its own contribution and remits both. Payment is due by the 15th of the following month. For October 2026 payroll, that means 15 November 2026.

Late payment is costly. The Act applies a surcharge on unpaid contributions for every month they remain outstanding.

Why the date moved

Contributions were originally due to start on 1 October 2025. In August 2025, the Thai Cabinet approved a one-year postponement, citing economic pressure on employers. A new Royal Decree confirmed 1 October 2026 as the start date, and pushed the rate increase to 2031.

That history matters. Some employer guides, payroll templates and vendor configurations still show the 2025 start and the 2030 rate step. Check yours.

What payroll needs to change

The percentages are small. The process is not.

1. Confirm your status. Count employees across the legal entity, and map which staff, if any, sit outside your provident fund.

2. Register. The DLPW accepts employer registration through its e-Service system.

3. Configure the deduction. Add the employee deduction and employer contribution as separate payroll elements. Build in the 2031 rate change now, so it is not a manual fix later.

4. Define the wage base. Contributions are calculated on wages. Confirm which pay elements count, and apply the definition consistently.

5. Show it on the payslip. Employees will see a new deduction. A clear line item and a short explanation will save HR a great many questions.

6. Diarise the 15th. Build the monthly remittance into the payroll calendar, with a named owner.

7. Plan for exits. Leavers are entitled to their balance. HR offboarding should capture the information the DLPW needs to pay it.

The provident fund question

For many enterprises, the EWF forces a strategic choice. A provident fund is voluntary, more generous and often a retention tool. The EWF is mandatory, modest and standardised.

Some employers will decide that extending or launching a provident fund is the better answer. Others will run both, for different groups. Either way, the decision belongs to HR and finance together, and it should be made deliberately rather than by default.

Where systems help

The EWF adds one more statutory calculation to Thai payroll, alongside social security, withholding tax and provident fund deductions. Each has its own base, its own rules and its own deadline.

An enterprise HR and payroll platform such as MiHCM Enterprise, delivered in Thailand with our partner iOperation, keeps those rules in one place, with the audit trail to prove it.

The Fund is live. The first deadline is close. The best time to get payroll right is before the first remittance, not after the first surcharge.
